Heavy handedness, as never broken one myself, and must have replaced hundreds of batteries, and probably repaired nearly as many fobs...

Happens all the time. I've spent far too much time on my hands and knees looking for customer's immobiliser chips. Every one of them had big bunches of keys, which is also true of worn ignition lock barrels.

Good point, actually. I think my keyring is due a cull.

Just put all the extras in the centre arm rest like James.. (Sorry James )

..............or get a handbag, sorry, manbag, as then you do not need to keep all your keys on one ring
